TOOL FOR REMOVING PERCHES FROM AUTOMOBILE AXLES.

Application filed August 27, 1921. Serial No. 495,882.

To all whom it may concern:

Be it known that I, HORRY E. Pinvm'r, a citizen of the United States, residing at Live Oak, in the county of Suwanee and State of lfilorida, have invented eertain n ew andusietul improvements in Tools for Removing Per hes from Automobile .\xl'es.'of wh,ich the following is a specification.

In attaching shock absorbers to ditferent makes of automobiles, especially the Ford, it is necessary to remove the perch from which the body spring is suspended. Inasmuch as these perches, which pass through the axle, have a very snug fit through the axle and frequently become rusted in. it is a very difticult matter to remove them and when heavy hammer blows are required to dislodge the perch such blows destroy the threads on the perch or the lower edge of the perch becomes so distorted that it cannot be again used.

The object of my invention is to provide a perch remover which will enable one to readily. and without great efi'ort, remove a perch without distorting the perch or its threads; and with this and other objects in view my invention consists of the parts and combination of parts as will be hereinafter pointed out.

In the. drawings:

Figure l is a front elevation ot' the portion of an axle of anautoinobile. with my invention applied thereto.

Figure 2 is a side elevation of Figure 1.

Figure 25 is a top plan view of Figure l, the perch being shown in section.

Figure 4 is a detail sectional view on the line l-'t of Figure 2.

The reference numeral 1. designates an axle of an automobile through which there are vertical openings near each end in which the perches 2 are sealed. The perches 2 are secured in the axle by means of the nut 3 which nut is mounted on the screw threaded lower end of the perch and bears against the under face of the axle. The ends of the body springs of the automobile are secured to shackles which in turn are suspended l'rom these perches.

M improu-d tool or device for removing the e perches comprises a standard or body portion i having an enlarged head 5 l'roln which arms 1?- project at. right angles to the body portion. aid arms at their tree ends bein otl's r fr m the general plane of the bodv il liic2?"!!13113lll littliltl at T. the arms being spaced so that they may straddle the body of the perch .2 as shown in the drawings.

A base member H extends at right angles from the standard in the same direction as, and parallel to the. body of the arms 6. its free end being provided with slots 9. A bolt 10 passes through the free end of the base 8 and straps ll are pivotally mounted on said bolt in the slots 5). the upper end of the straps 11 fitting into the tlorkcd ends 12 of the arms 6 and clamped in such position by means of the wing nuts 13. The base member 8 is widened at. its free end portion as shown. These widened portions of the standard and base enable inc to secure a comparatively wide bearing for the tool or device on the axle to resist all tendency of the device to twist or work loose when in use. The standard 4 is provided with a set screw 14 to hold the device sung to the axle.

A screw threaded thrust rod 15 is passed through an opening in the base 8 and a bevel .gcar wheel H3 is rcvolubly mounted on this rod above the base H. the gear wh cl having threaded engagement with the rod.

stub shat't lT projects laterally from one side of the standards t on which a IUlllbined ratchet and bevcl gear whccl'lh 'is,, revolubly mounted. the bevel gear portion engaging the teeth of thc bevel gear wheel 16. .\n operating handle 11! is |ooscl iournallcd on the stub shaft [7 and is provided with a nose 201m which nose a ratcbct dog ll is loosely )ivotcd. said dog being olh-ict I at one end to uing it in alignnu-nt with the ratchet wheel 18. cotter pin 2; holds the handle 1!! on the stub shaft.

The not .i of the pcrch having been removed. my device is titted around the axle as shown and clamped in position. the bandle 19 is operated, whereupon the dog 21 revolves the ratchet wheel IR the bevel gear thereof revolving the evel gear 1o, whereupon the rod 15 is elevated to a position with its end abutting the end of the perch 2; continued operation of the handle 19, through the operations u. t described causes t he rod 15 to progress in its upward movement against the lower end of the porch 2. thereb positively l'orcing the perch out of the axle in a minimum amount of time without great manual ell'ort and avoiding distorting the lower end of thc perch or its threads. so that the perch n|a again be used.

I am aware that some changes may be made in the details of construction without departing from the seope oi the appended claims.

'hat 1 claim is:
